Abstract
Abstract A digital printing apparatus is disclosed for printing on a receiver a postal image having invisible embedded information in response to a digital image having a plurality of pixels each having at least one pixel value and input information to embedded. The digital printing apparatus receives the digital image and the input information. The receiver includes a plurality of perforated peelable portions or a mailing envelope. The apparatus responds to the input information and the digital image for modifying a predetermined number of pixel values of pixels in the digital image with the input information so that the input information is embedded in the digital image and prints a postal stamp image on the receiver in accordance with the modified digital image having the embedded information wherein the embedded information is invisible to unaided human eyes that can subsequently be extracted.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
139 words
A digital printing apparatus for printing on a receiver a
postal image having invisible embedded information in response to a digital image
having a plurality of pixels each having at least one pixel value and input
information to embedded, comprising a) means for receiving the digital image and the input
information; b) the receiver including a plurality of perforated peelable
portions; c) means responsive to the input information and the digital
image for modifying a predetermined number of pixel values of pixels in the
digital image with the input information so that the input information is embedded
in the digital image; and d) means for printing a postal stamp image on the receiver in
accordance with the modified digital image having the embedded information
wherein the embedded information is invisible to unaided human eyes that can
subsequently be extracted.
Claim 2
Dependent Claim
15 words
The apparatus of the claim 1 wherein the printing means is
a thermal resistive printer.
Claim 3
Dependent Claim
15 words
The apparatus of the claim 1 wherein the printing means is
an ink jet printer.
Claim 4
Dependent Claim
41 words
The apparatus of the claim 1 further including an extraction
system for digitizing the postal image printed on the receiver, and extracting the
embedded information from the digitized image, and for displaying human
readable information corresponding to the extracted embedded information.
Claim 5
Dependent Claim
56 words
The apparatus of claim 4 wherein the extracting system
includes a scanner for digitizing the postal image on the receiver, a processor for
extracting the embedded information from the digitized image, and a display
device, the processor selectively applying the extracted information, or the
digitized image, or a combination thereof, to the display device for viewing.
Claim 6
Dependent Claim
136 words
A digital printing apparatus for printing on a receiver a
postal image having invisible embedded information in response to a digital image
having a plurality of pixels each having at least one pixel value and input
information to embedded, comprising a) means for receiving the digital image and the input
information; b) the receiver is a mailing envelope; c) means responsive to the input information and the digital
image for modifying a predetermined number of pixel values of pixels in the
digital image with the input information so that the input information is embedded
in the digital image; and d) means for printing a postal stamp image on the receiver in
accordance with the modified digital image having the embedded information
wherein the embedded information is invisible to unaided human eyes that can
subsequently be extracted.
Claim 7
Dependent Claim

The apparatus of the claim 5 wherein the printing means is
an ink jet printer.
Claim 9
Dependent Claim
41 words
The apparatus of the claim 1 further including an extraction
system for digitizing the postal image printed on the receiver, and extracting the
embedded information from the digitized image, and for displaying human
readable information corresponding to the extracted embedded information.
Claim 10
Dependent Claim
56 words
The apparatus of claim 4 wherein the extracting system
includes a scanner for digitizing the postal image on the receiver, a processor for
extracting the embedded information from the digitized image, and a display
device, the processor selectively applying the extracted information, or the
digitized image, or a combination thereof, to the display device for viewing.
